f-Edge

f-Edge is a 3ds Max plug-in that gets rid of the sharp and flat edge look of standard angular objects.
As in the real world, f-Edge simulates the slight soft curvature over the selected edges of the object.
It comes with a very small rendering time penalty and gives that non-"computer generated" soft look to the object.
Especially suited for large-scale city and architecture projects where edge smoothing by hand is almost impossible.

To register, you need to purchase a license from share-it.
NOTE: you don't need a license for network rendering with f-Edge, just for the workstations where the f-Edge settings will be modified in Material Editor.
